WINDOW STAY Filed Aug. 19, 1929 Patented Feb. 24, 1931 UNITED STAT-esTHOMAS PETER EUSTEGE, OF WELLINGTON, NEW ZEALAND wnvnow sTAY'Application filed; August 19, 1929, Serial F0. 38G,8$0,and'in N ewZealand September 11, 1928. i

This invention relates to casement stays for, windowsand the like ofthekind in which the stay bar .is pivoted in a link pivoted to a bracketfixed to the sash'and passing through a bracket attached to the windowframe, the end of the stay bar adapted, when f the bar is turned atright angles thereto, to retain the sash in its closed position. 7

According to the present invention, the

bracket fixed to the window frame has projecting lugs in which ispivoted a vertical member on pins, passing through such member and thelugs so'that such vertical member may rotate therein. through themember, being adapted to slide freely therethrough, while the linkpivoted to the bracket on the sash is also adapted to pass through themember. A pin traverses the member near the lower end and notches in thebottom edge of the stayare adapted to engage over this pin. When thesash isf closed the stay is adapted to assume a vertlcal position sothat the bottom edge of the stay The invention will now be describedwith the aid of the accompanying drawings where 5 Figure 1, is a sideelevation of the stay on, a window showing it in its closed and lockedposition. 7

Referringtothe drawings, the bracket 1'55 f'zied'to the window frame 2has'projecting lugs 8'in which is pivoted a vertical member] l on pins5"fixedin the lugs 3 and passing through the n'i-emher so that it mayrotate thereon; .i' The stay bar 'Gpasses freely through so this member,whilethe link 7, to which is 'pivotedthe bar 6 on its pin 8, i'spivotedon v a pint) In a bracketlO fixed to thesash ll.

r Apin l2traverses the member 4 near the lower end and notches 14 in thebottom edge e of the stay are'adapte d to engage over this pin'to retainthe sash in different open posit1OI1S, f

When the sash is closed, as shown inFigv ures land 2, thestaybarassumesa vertical position .so that the bottomfedge or; the bar bears againstthe lower edge of the member,

as shown in Figure 1, thereby assisting in retaining the sash closed.The link 7 is formed with-two vprojecting tongues 15 and 1 '16 parallelwith {the linkand'just above it,

but yieldable to open and close. These tongues pass through the pivotedmember at and, when the stay bar is rotated to a vertical pos tion, asshownin Figure 1, the upper proectmg end 17 oflthebar will enter betweenthe tongues and expand them against the inner sides of the member. Thetongues 15 and 16 have outwardly curved or bent portions 18 which,whenthey are expanded by the end i 1 7, will engage against the edges ofthemember shown in dotted'lines in'Figure 5. In

this figure, however, the ends of the tongues are continued in portions19 which enable them to enter the member and be slightly f" compressedduring the passage therethrough, and spring upwards's'o as just toengage the outer edges of such member, as shown in full lines'in'Figure5, and upon the bar 6'being rotated to its verticalposition,'-th'e end 17 will pass 'up between the tongues and further'force out the tongues against the inner sides of the "members (shownin: dotted lines), draw ng up the sash and locking it in this p0s1t1on.-:Th-rs forms aflock to prevent the 'Figure 9," is a sectional plan alongline V window being opened from theoutside. The

end 17 is shaped so as to readily enter between the tongues and may beof the shape indicated in Figures 2 and 3, that is the top front edgebeing narrowed as indicated at 20.

of locki g is shown. In this case, the sides of the men be'r are formedwith a narrowed part normal pressure.

In F igmres 7, 8 and 9, an alternative form by bendmg the sides'inwards,as shown at 21,-

one side of the member being cut asat 22 so that this side of the.member will form a spring to permit the end 17 of the stay bar to passthrough. The end of the stay bar'17, on being rotated, to a verticalposition, will enter the narrower portion through which it passes, andthe sides returning, the edges of the narrowed portions 21 will form astop for the end 17 of the stay bar, as shown in Figure 9. This willretain the window closed against raised, the end 17 will be. forcedthrough the narrowerportion, thus enabling the window sash to be openedas above described. Lips 23 on the narrowed portions ensure the end '17being guided into. the narrower portion of the member.

The sides of the link 7 may be slightly closed at'their lower edges,'asshown at 24 in Figure 4:,so that when the end 17 passes between thesides of the link upon the stay 6 being raised to a horizontal position,such end 17 will tend to hold down the stay and retain the bar in aposition on the pin 12.

That I claim is r 1 Upon the bar 6 being.

them apart when stay bar is being moved to open the sash.

3. In a stay as clalmed 1n claim 1, wherein the projecting end of thestay bar is shaped so as to easily engage the pressure members and forcethem apart when passlng between such pressure members.

In a stay as claimed in claim 1, wherein the pressure members consist ofyieldable tongues forming part of the link and pass be- "tween the sidesofthepivoted member so as to be expanded against the sides of saidpivotedmember by thestay bar and outwardly extending terminal portionson the pressure members to engage behind the said pivoted .oisaid staybar as the latter is 'beingmoved into engagement therewith.

In testlmony whereof, I have slgned my name to thlsspecification.
